C3925-CME-SRST/K9 Use Case
Branch Office Voice Continuity with C3925-CME-SRST/K9
A national retail chain deploys the C3925-CME-SRST/K9 voice bundle with PVDM3-64, FL-CME-SRST-25 and UC License PAK at each branch to provide localized call processing and automatic PSTN fallback if the WAN link fails. In a real-world outage scenario, SRST seamlessly takes over call control, maintaining 100+ concurrent voice sessions and preserving business continuity. Benefit: Ensures uninterrupted customer service, reduces revenue loss from downtime, and consolidates voice and data infrastructure on a single Cisco 3925 platform.
On-Premise Unified Communications Migration for Financial Services
A mid-sized financial services firm transitions from aging PBX systems to Cisco CME on C3925 hardware. Leveraging the PVDM3-64 DSP module, UC License PAK and FL-CME-SRST-25, the firm runs full VoIP routing, conferencing and SRST on a single router. In practice, engineers provision 200 SIP endpoints and enable advanced telephony features—hot desking, voicemail and secure SIP trunking—while retaining local call processing during downtime. Benefit: Delivers enterprise-grade voice services, reduces TCO by 30%, and accelerates time-to-market for new communication features.
Hybrid Cloud Voice Gateway for SMBs with UC License PAK
An IT services provider implements a hybrid cloud voice solution for an SMB client using the C3925-CME-SRST/K9 bundle as the on-premises gateway. The PVDM3-64 module powers 150 voice ports, while UC License PAK unlocks Cisco Unified Communications features and FL-CME-SRST-25 ensures local telephony during cloud provider outages. The gateway connects Webex Calling to the PSTN, preserving call quality and compliance. Benefit: Offers seamless failover between cloud and landline, optimizes bandwidth usage, and simplifies management via a consolidated Cisco router platform.
